This invention relates to spools for Axminster. looms and it--is thegeneral object of the invention to provide improved means to secure abearing gudgeon to a spool so that the gudgeon will be held againstundesired rotation relatively tothe spool as the latter issupportedeither in a winding frame or in an'AXminster loom. 7

In my prior Patent No. 1,683,2241' have shown a'spool for use inAxmins'ter looms jwhereina wooden barrel has parallel grooves cut acrossthe end thereof to receive correspool head. A bolt or gudgeon formedwith 1 an enlarged bearing element passes through the. steel headinto-the wooden barrel and is the means by which the head issecured-tothe spool. The corrugations very effectively prevent rotation'of the steel head with respect to the barrel, but under someconditions-I find thatthe gudgeon has a tendencyto work loose and it 'isan importantobject of" my present invention to provide a washer-orsimilar device which willhe held against rotation by the aforesaidcorrugations and at the-same time will be so related to the gudgeonas{to prevent angular movement thereof. r

" It is'a more particular object of my present invention to providebetween the corrugated steel head and the enlarged'bearing portion ofthe gudgeon a washer having lugs t'o extendinto the corrugations of thesteel head and having also atongu'e which may be'deiiected to enter anyoneof a plurality sition serving eifectively to hold the several partsof the spool against 'relative angular .motion, 7 With these and otherobjects in view which invention resides in the combination andarrangement of parts hereinafter set forth and described in the clanns.

In the. accompanying drawing wherein ;a

convenient embodiment of my. invention is set forth,

j.l' Fig'..-1;is atop plan view of aspool made of Fig. 3, spondingcorrugations struck from a fiat steel according to my present inventionand adaptable for use in an Axminsteriloom,

' Fig. 2 1s a new on an enlarged scaletaken 111 the same dlrectlon asFig. 1 showing the steel head, gudgeon securing lug for the latter andthe washer, said parts being separated and partly in section toillustrate the aforesaid notches, 7 r 1 Fig.3 is an enlarged plan of oneend of the spool shown in Fig. 1,

Fig. 4 is a vertical section on line 4-41 Fig. '5 is a horiaontalsection taken on line 55 of Fig. 4,

rection of arrow 6, Fig. 4, and r r F1 g. 7 is-a detailed perspectiveview of the washer. A spool of the type to which my invention relateswill ordinarily include in its construction a cylindrical barrel-1Oprovided thepresent instance are preferably macle of steel and formedwith a plurality of parallel "spaced corrugations 13 which as shown inFig.6 may extend across the central portion of the head. f

These corrugations fit into corresponding grooves 14 which extend acrossthe ends of the barrel, said grooves being spaced apart a properdistance to receive the several corru- V V 'gations. The ends of thespool are preferof notches formed in the'bearin'g portion of thegudgeon, said tongue when bent into po-- ably made alike so far as thecorrugations of the' steel headare concerned and may be made alike sofar as other features to bedescribed dare conoerned. Ears 15' are struckfrom the steel head andextend into engagement with" theside parallelwalls of the slot 11.

will appear as the description proceeds, my I bore 18 of thebarrel andhaving preferablyia reducedportion19 which may be threaded into ametallic block 20. The latter. mayllie in a lateral aperture 21 whichintersects the .bore'18j-as shown in Fig. 5 and each block'isl Fig. 6 isan end elevation taken in the di 65 My improvements relate particularlyto'the f means for preventing relative rotary motion between the barrel,or more properly the block 20,: and the gudgeon,:and in carrying myinvention into'effect. I interpose between bearing portion 23 and thecentral portion of the steelhead awasher ofthe general form shown inFig- T-and designatedat 30. Said washer may have one or more small lugs31 proportioned to enterone or another of the corrugations 13 whichextend inwardly from the :outer plane face of the head 12. The washer isprovided with a bore 32 through which extends the body portion16 ofthe'gudgeon. The lug or lugs 31 act to prevent relative-movement-of thewasher with respect to the head 12.

The washer is further provided with a tongue 33 which is proportioned toenter a notch 34 formed in the bearing portion 23 as shown in Figs. 2and 4. .There may -be several of these notches although-I haveshowniherein only two, but I do not wish to be limited to a singletongue 33 on the washer.

In assembling the several parts-of the spool the steel head will firstbe fitted to the end of the spool with the corrugations l3 properlyreceived by the corresponding grooves in the barrel. The washer 30 willthen be placed so that its bore 32 will align with the bore in:thecenter of the steel head and the gudgeon will be passed through'saidwasherand st'eel head. The block 20 which may have previously beeninserted in the passageor aper- "ture 21 will receive the threaded endsof the g u dgeon and thelatter will be turned until the gudgeon isalmost in its final position. The lug or lugs 31will then be-alignedwith the corresponding corrugations and the gudgeon threadedinto theblock until tight. 'The parts will be tightened. until one of thenotches 34 is in alignment with the tongue 33, after which the-latterwill be bent into the adjacent notch by a suitable tool. By

this last operation all of the parts of the spool will be held againstrelative rotary motion and the gudgeon will not be able to turn in thebore 18, with the result that the steel heads 12 willbe held accuratelyin position so that the warp threadsywound on thebarrel 10' will occupyan accurately-"defined warp space.

I From-the foregoing it will be seen that- I will be seen that changes vand :mOdifications may be made therein by those skilled in the artwithout departing from the spirit and scope of the invention and I donot wish to be limited'to thedetails herein disclosed, but whichI claim:is: y j

. L In-aspool having ahbarrel provided with grooves across the 1 endsthereof and having gudgeon extending from 'thebarrel provided with abearing surface having a portion thereon to engage acomplementarily'fo-rmedgudgeon on an adjacent-spool, a

spool head substantially perpendicular. -to the axis "of the barrel andhaving corrugations oncone side-toenter the grooves and correspondingrecesses onthe opposite side,

said fgudgeon extending -through the head 1 and secured at its inner end;with respect to the barrel and having. a cylindrical bearing surface,means defining a slot in the-bearing surfaceof the gudgeon,-and a memberlying within :the periphery of the bearing surface -and'havingt aportion to extend into the. slot to rprevent. angular movement. betweenthe member. and gudgeon, and additional .means on the-member to holdsaid member against relativeangular movement with respect to the spool.
